Интерфейсные элементы - Расширительные модули ввода-вывода PCF8575PWR

Расширитель I/O , 16бит, 400 кГц, I2C, SMBus, 2.5 В, 5.5 В, TSSOP

The PCF8575PWR is a remote 16-bit I²C and SMBus I/O Expander with interrupt output designed for VCC operation. The PCF8575 device provides general-purpose remote I/O expansion for most microcontroller families by way of the I²C interface (serial clock (SCL), serial data (SDA)). The device features a 16-bit quasi-bidirectional input/output (I/O) port (P07-P00, P17-P10), including latched outputs with high-current drive capability for directly driving LEDs. Each quasi-bidirectional I/O can be used as an input or output without the use of a data-direction control signal. At power on, the I/Os are high. In this mode, only a current source to VCC is active.
